WRE CH.

To all whom it may concern:

Be it known that we, BURTON B. CHASE and EMMETT VAN SIOKLE, citizens ofthe United States, residing at Port Jervis, in the county of Orange andState of New York, have invented new and useful Improvements inWrenches, of which the fol lowing is a specification.

This invention relates to wrenches, and

has for an object to provide a device of this character which willinclude a mov able socket and means for securely holding the socketagainst movement in one direction when the socket is engaged with thenut and the wrench operated for the purpose of loosening the nut from abolt. p In the drawing, forming a portion of this specification and inwhich like numerals of reference indicate similar parts in the several'views :Figure 1 is a side view of the wrench with the face plateremoved. Fig. 2 is a section on line 22 of Fig. 1.

()ur improved wrench comprises a handle member 1 which is provided atone end with a substantially cylindrical portion 2. The walls ofthe'cylindrical portion 2 are provided at one side with an inwardlyextending annular flange 3 and at the opposite side the walls of thecylindrical portlon are provided with an outwardly extending'flange 4..The, flange 3 is provided with a central opening 5 which is disposed inline with the opening 6 in the head 7. The head 7 is disposed inparallel relation to the flange 3 of the cylindrical portion 2 of thewrench, and as shown, said head is detachably secured to the outwardlyextending flange 4 by screws or other such equivalent fastening devices8; 1

A member 9 is revolubly mounted in the cylindrical portion 2, beingconfined betweenthe head '7 and the flange3 thereof,

the latter having formed thereon an inwardly extending annular bead 10which bears against one side of the member 9 as shown. The member 9 isprovided with h Specification of Letters Patent. Application filedAugust .8, 1911.

peripheral teeth 11 which are spaced from each other to define pockets12 in which the spherical locking elements 13 are engaged. The walls 14of the pockets which are defined by the teeth of the element 9 areinclined outwardly in the direction of the surface 15 of the cylindricalportion ,2 so that -when the handle 1 is actuated in one direction the,friction bodies 13 will travel on the inclined surfaces 14 of thepockets and be brought into effective frictional contact with thesurface 15 so as to cause an effective locking of the element 9 andsecurely hold the same against rotation in one direction. The member 9is provided with v the oppositely extending nut engaging sockets 16 and17 which extend throughthe passages 5 and 6 respectively, hereinbeforedescribed. The walls of the member 2 are inclined outwardly, at 18,'fromthe surface 15 so as to extend in the direction-of the head 7. Thisconstruction is such that a relatively large passage is provided betweenthe innermost portions of the pockets I 12 and the said surface 18 wasto facilitate the insertion of the bodies 13 in said pockets or theremoval ofsuch bodies therefrom. We claim:

A wrench comprising a handle having an integrally formed cylindricalmember, the walls of said cylindrical member being pro- .videlil at oneend with an inwardly extending flange provided with-acentral opening I gweenie ripheral pockets therein, spherical bodies 16- In testimonywhereof We aifix our signaeated in sgiiddpockits, andin wardlz 1extendigig tures in presence of two Witnesses.
